Treibmittelbetätigtes Dampfdruckentlastungsventil für Kernreaktor

摘要

A nuclear fission reactor combined with a propellant actuated depressurization and/or water injection valve (38) is disclosed. The depressurization valve releases pressure from a water cooled, steam producing nuclear reactor when required to insure the safety of the reactor. Depressurization of the reactor pressure vessel (14) enables gravity feeding of supplementary coolant water through the water injection valve to the reactor pressure vessel to prevent damage to the fuel core (16).
